- 'TALKING-mom To all whom t may concern:

Be it known that I FRANK MALOCsAr, a citizen of the United tates, residing in the borough of the Bronx, city, county, and State of New York, have invented certain new and useful Improvementsin Talking- Machines, of which the following is a speci i ication.

My invention relates to talking machines, anddmore particularly to that type of such l machines which employs a disk record carried on a revolving turntable driven by a spring motor which must be wound u by a manual operation, and has for its object to produce a device which will 've an indi- 1 cation as to when the motor is 1n need of rewinding.

.AnotherA object is to so design and construct the apparatus that when there is not sufficient sprin power to play the record on the turnta le, the machine cannot be started.

A further object is' to produce a device which will render itunnecessary to rewind the motor until it has run down to such an extent that it williiot have sulicient power t0 lplay a full record.

further object is to prevent the motor running down and stopping after a recordv has been started and before it haa been finished.y y

These and further objects will more fully lappear in the lfollowing speciiication and accompanyin drawings considered together or. se arate y.; f/ A,

board of a cabinet of any approved construction, which is carried on side members 2, 2. Securedto the under side of the-board 1 is a frame 3, carrying a spring motor 4. The motor comprises a pair of spring barrels and 6 which inclose a heavy s iral spring. vThe outer end of the spring 1s attached to the barrel member 6 and the inner end is secured to the barrel member 5. A winding shaft 7 journaled in the frame eX- tends througha side member of the casing, and is provided with a screw threaded portion for the reception of a crank, by means of which the motor may be wound. The inner end of the shaft 7 carries a spur pin ion 8 which meshes with a face gear on the barrel member 6 to rotate the latter and wind the spring.

The winding .shaft is provided with a ratchet wheel'9 which is engaged by a gravity pawl 10 preventturnlng ofthe winding shaft'whenthe "springis unwinding.

The pawl is raised from the ratchet wheel during its forwardvmovement by the engage-v application. The Vbarrel member 5 carries a spur geen 11 which meshes with a pinion 11EL on a counter s'haftflQ which also carries a spur geai- 13 in'mesh with a pinion 14. on a turntableshaft- 15.

- The sizlaft I jfprojects throughthe top 1 of the e sing, and has removably secured s thereto turntable 16 on which rests ajdisk 1f; The shaft 15 has geared thereto a goverrop` 18 which is regulated by means of a cra k lever operated from the upper sidesoi:f 'etop1.`

A brare lever 19 is mounted onthe top 1 enf1 ca iies a brake shoe 20 which is adapted t eng ge the periphery of the turntable and i .'event rotation'thereof. The brake shoe is normally held inengagement with` the turnftablelbymeans of a vspring 191'and'i's provided with an operating handle 2.1"andjva'ith a latch`22 to hold it out of engagementwith the turntable and allow thelatter to bjrotated'byf ineens of themotor spring.

Loosely mounted on the shaft 7 at one side of the frame 3 and lever 23, and this lever carries ay stud 24 to which the'pawl 10 is pivoted. The stud eX- horn cdncealed in the tends-,through the frame 3 which is providedv with a, slot 25for` this purpose. acts as astop to limit the sidewise l of the lever 23. lThe lever 23 vhas attached The slot to .thez end thereof a helical sprin 2tr,.the

otherlid of-which is secured to t e under backward teli@ swing the lever movement-,is resisted by one' side,4 and this the spring 26. y

VPivoted tothe under side of the top land'.

extending across the motor inthe embodiment illustrated, is a lever 27, one 'end 28 of which bears against the lever 23 at the side` opposite the point' of attachment of theV spring 26. A -spring29 holds the end 28 of the leven 27 in'engagement with .the lever The'opposite end of the lever 27 is provided with a lip` 30 adapted to engage a.I notch 31 in the end of an arm 32, carried on the lower end of the shaft 33 of the brake" lever'19 as .shown in Fig. 6 Vand inl dotted lines in Fig. 3.' A stop 34C is provided toA limit the movement jof the arm 32.

y Il`he spring 26 is'so 4propoltloned that when the motor spring is wound to its full extent when it is Wound, records may be` its tendency l to rotate ',thiiwindingl shaft backward will engage, the ratchet 9. with the pawl 10, and move the' lever 23 against the tension of the spring 26, but when the motor spring has run down to such an extent'thatit will not rotate the turntable long enough to cause the stylus of the sound-box to traverse the entire record carried on the'largest disk which may beused on the machine, the tension of the spring 26 will `overcome that of the motor spring and move the lever23 in the opposite direction.

The operation of my Improved device 1s as follows:

1 Thel motor is e uipped with a long running spring capa winding, agreat number vof records, and played, and whenit is desired to .change records and needles, the brake is applied and the motor stopped. When a newrecordis in place the brake is released and the record is rotated under'the stylus.

v sion of the motorspring wi 1 rvagainst that as' rin of the lever1`2 y rwill be movedagan es Spring 29a :fthe 30 will When the records are beinV :played'the tenof the spring 26, `the lever23 will be lmoved of the rae-af e@ am extending upward is a4 movement. .I

le of playing, withone overcome that and against the endl 28 he last mentioned., lever brake is applied to stop the motor. it may be released withoutl the arm coming' in contact Awith the lip 30. When, however, the motor spring has run down to such an extent that it will not drive the turntable long enough 4to cause the stylus to traverse the record groover on the largest diskcapable of being used on the machine, the ltension of the [spring 26will overcome that of the motor s and pull the lever 23 to the right in 1E, 2, and away from the end 28 of the long ."'jlevef 27,. lThe SPl'Il 29 will pull the short .endy28 ofthe lever 2 vto the right in Fig. 8, vand'bring the lip 30 into the path of the armv .32. ,'When the, brake is now applied to stop. the motor, the rounded end of the arm 32 will engage thel'lip 3() and move the lever-27 to .the right in Fig. 3, against the tension of the spring 23,.` When the nctchl comesoppd site the lip 30 the spring 2,@ will swing the lever tothe left as' Shown in dotted lines in Fig. 3, the nctchlin the arm will engage the `lip and the brake willbelocked against the turntable and cannot' be released. The brake' ingnd the brake cannot be released until the motor l spring 1s rewound to such an extent that its tenslon will overcome that of the spring 26, and move the lever '23 tothe left in Fig. 2, which) inturn will swing the lever 27 against the tension of the spring 29, and Ymove the lip 30l vfrom the. path of the end of the arm 32. In' accordance with the provisions of the patent statutes, I have described the principle of my invention together with the apparatus which I now consider to represent ,the best embodiment thereof,but l desire to have it 'understood that theapparatus shown is merely illustrative, and that the invention can be carried out in other ways Without departing from the spirit; of my invention.v
